The laser beam will spread 3.5 feet in 1000 ft (1/5 mile!) and register
your speed in 1/4 to 1/2 second.  (I know *I* don't have reaction
times this fast!)  And of course there will be no *radio* leakage.

BTW, they aim the device with a telescopic scope.  The same type used
on hunting rifles.  (Let's see... Put that red jag in the crosshairs
and squeeze the trigger... :-)
